Embodiment 1

[0036] Such as Figure 1~Figure 6 As shown, an installation method of a high-altitude large-diameter pipeline in a complex environment includes the following steps:

[0037] A, make track support: track support comprises triangle support frame 1 and the sliding track beam 2 that is arranged on the top of triangle support frame 1, is provided with the track bar as slipping trolley track on the top surface of sliding track beam 2, track The bar is made of a strip-shaped steel plate, and the long side of the track bar is parallel to the long side of the sliding track beam 2 .

[0038] b. Place a hoist on the ground, hoist the track support to the designated position on one side of the pipe support 4 through the hoist, and fix the track support to the pipe support 4 by welding. If the site environmental conditions permit, a 25t car can be used Carry out the hoisting of the track support, that is, when the construction site can accommodate 25t cars in the on-site environment, a 25...

Embodiment 2

[0049] Such as Figure 1~Figure 6 As shown, a hoisting device for a high-altitude large-diameter pipeline in a complex environment includes a track support, a sliding trolley, an electric chain-down 10 and a hoist.

[0050] The track supports are two groups, and the two sets of track supports are installed on two adjacent pipe supports 4, and each set of track supports includes a triangular support frame 1 that is relatively arranged on both sides of the pipe support 4 and is horizontally arranged on each triangular support frame. 1 Sliding track beam 2 at the top.

[0051] The sliding dolly is arranged on the top of the sliding track beam 2, and a suspension rod 11 is arranged at the top of each sliding dolly. The quantity of the sliding trolleys arranged on each group of track supports is three, two of which are respectively arranged at the middle part and the free end of the horizontal direction of the sliding track beam 2 on the pipe butt joint side of the pipe support 4,...

Abstract

The invention provides a method for mounting a high-altitude large-diameter pipe in a complex environment. The method comprises the following steps that 1, a track support is produced; 2, the track support is hoisted and mounted; 3, the step 1 and the step 2 are repeated, and each track support is welded to the other side of a pipe support; 4, sliding trolleys are produced; 5, the sliding trolleysare continuously hoisted to sliding track beams through a winch; 6, the step 1, the step 2, the step 3, the step 4 and the step 5 are repeated, and the corresponding track supports and the corresponding sliding trolleys are mounted on the other pipe support; 7, each first main sliding trolley is connected with an end pipe segment through an electric chain block; 8, one end pipe segment is hoistedto one side of a pipe bracket through the electric chain block on the corresponding first main sliding trolley, and the corresponding first main sliding trolleys and a subsidiary sliding trolley arehorizontally moved through the winch; 9, the step 7 and the step 8 are repeated, and the other end pipe segment is hoisted a pipe bracket of the other pipe support and mounted in place; and 10, a middle pipe segment is lifted through an electric chain block till the middle pipe segment is in butt joint with the end pipe segments to be mounted.

Description

technical field [0001] The invention relates to a high-altitude large-diameter pipeline installation technology, in particular to a high-altitude large-diameter pipeline installation method and a hoisting device in a complex environment. Background technique [0002] Conventional high-altitude large-diameter pipeline installation adopts prefabricated pipelines on the ground, with a prefabricated length of 20-30 meters, and then uses a large-tonnage crane to hoist the prefabricated pipelines to the pipe support on the pipe support. The pipe support is the pipe bracket. However, in a complex environment, due to the limitation of the site conditions and the limitation of the manufacturing process, it is impossible to carry out the prefabrication of the large-diameter and long pipeline according to the conventional method and then hoist it in place. There are also large-diameter long pipelines divided into multiple sections, and then hoisted to a designated position after assemb...
